Li-ion battery R0 value

Hi,

I trying to simulate li-ion battery aging cycle in simulink. Battery initial R0 value is taken from datasheet, let know to how calculate R0 value after 100 or 250 cycles. Is any formula is available for calculating R0 value based on cycle.

Hello Nalla,

The R0 growth will depend on the type of cell, operating and environmental conditions. It is information you need to provide the model with as a growth per N cycles. This aging rate is then used by MATLAB to inform you of the degradation after an arbitrary cycle. Some battery manufacturers provide this information, but not always.

Hello Javier,

If any formula is available for calculating R0 value based on initial value and no of cycles
